需求：传入两个经纬度计算两点之间的距离

1.导入依赖的jar

<!--计算距离依赖的jar-->
<dependency>
	<groupId>org.gavaghan</groupId>
	<artifactId>geodesy</artifactId>
	<version>1.1.3</version>
</dependency>

2.简单的工具类

import org.gavaghan.geodesy.Ellipsoid;
import org.gavaghan.geodesy.GeodeticCalculator;
import org.gavaghan.geodesy.GeodeticCurve;
import org.gavaghan.geodesy.GlobalCoordinates;
 
/**
 * 计算经纬度直线距离
 * @author: xiaoyc
 */
public class LonLatUtil {
 
    public static double getDistanceMeter(GlobalCoordinates gpsFrom, GlobalCoordinates gpsTo, Ellipsoid ellipsoid) {
        //创建GeodeticCalculator，调用计算方法，传入坐标系、经纬度用于计算距离
        GeodeticCurve geoCurve = new GeodeticCalculator().calculateGeodeticCurve(ellipsoid, gpsFrom, gpsTo);
        return geoCurve.getEllipsoidalDistance();
    }
 
}

DEMO

import com.xiangwang.utils.LonLatUtil;
import org.gavaghan.geodesy.Ellipsoid;
import org.gavaghan.geodesy.GlobalCoordinates;
 
public class MeterTest {
 
    public static void main(String[] args) {
         //用户当前坐标
        GlobalCoordinates userSource = new GlobalCoordinates(49.978957, 116.419715);
        //店铺位置坐标
        GlobalCoordinates businessTarget = new GlobalCoordinates(49.986348, 116.493068);
        double meterDouble = LonLatUtil.getDistanceMeter(userSource, businessTarget, Ellipsoid.Sphere);
        System.out.println(meterDouble);
    }
 
}
